Around the world, airports now include exhibitions that demonstrate the region's culture or simply add visual interest to highly trafficked terminals. Some, like Singapore's airport, use computer technology to animate the art, while others, like an installation in Los Angeles International Airport, rely on folded paper to create a one-of-a-kind design.

We've scoured the web to share some of the coolest airport art installations below:

In Keflavík International Airport in Iceland, a stained glass mural decorates the building's sloped roof.

In 2014, London's Heathrow Airport installed a sculpture called "Slipstream" by British artist Richard Wilson. The sculpture, which is suspended 59 feet above the ground in the airport's Terminal 2, mimics a stunt plane's flight path. It weighs 77 tons, and is 256 feet long.

A jellyfish-like installation hangs from the ceiling of Terminal 2 in San Francisco's airport. The sculpture, created by Janet Echelman, features bent steel covered in pink and purple paint and hung below skylights. Travelers see the installation immediately after exiting airport security.

You can find "Elevate" by Joyce Dallal in Los Angeles' airport. The paper plane art was made from Japanese paper printed with excerpts the Universal Declaration of Human Rights and third and fourth Geneva Conventions.

Chicago's O'Hare Airport has a moving walkway decorated with neon lights. "Sky's the Limit" was installed in 1987 and includes 466 neon tubes and 23,600 square feet of mirror to reflect the mile-long artwork onto Terminal 1.

San Jose's airport has a piece of hanging LCD art called "eCloud." It's made from polycarbonate tiles that transition between transparent and opaque states, depending on weather conditions from around the world.

Philadelphia International Airport used to hold these beer-bottle clocks in Terminal A. The mechanism was designed by Rick Stanley and his son Vince of Stanley Clockworks and uses 300 recycled Yuengling bottles to create a 21-foot long working time system.

Sculptor Peter Shelton built "Clouds and Clunkers" out of plastic, stainless steel, and cast iron. It was placed in Seattle-Tacoma International Airport in 2006 and assembled on a set of bleachers, where passerby were encouraged to sit and relax among the clunkers.

Denver's airport is its own piece of art—the terminals' roofs are topped with 21 tents that resemble the Rocky Mountains. Each tent is made out of white fiberglass fabric.

In Terminal 1 of Singapore's Changi Airport, travelers can see "Kinetic Rain," a 246-square-foot installation with 1,216 bronze raindrop shapes. The raindrops hang from steel wire on the ceiling and move in computer-controlled patterns to give a synchronized, floating effect.
